Changes

• Fixed building of EDS-typed cluster endpoints with domain address. (Issue #50688)

• Fixed custom injection of the istio-proxy container not working properly when SecurityContext.RunAs fields were set.

• Fixed a regression in Istio 1.21.0 causing VirtualServices routing to ExternalName services to not work when ENABLE_EXTERNAL_NAME_ALIAS=false was configured.

• Fixed a behavioral change in Istio 1.20 that caused merging of ServiceEntries with the same hostname and port names to give unexpected results. (Issue #50478)
